https://www.ted.com/talks/zoe_karl_waithaka_got_millet_how_marketing_could_improve_the_lives_of_african_farmers

From "got milk?" to "avocados from Mexico," marketing influences what you eat more than you may realize. But despite the known power of food marketing, farmers in Africa are more likely to receive funding for seed and fertilizer than they are for advertising geniuses. Agricultural development expert Zoë Karl-Waithaka outlines three ways industry, governments, NGOs and others can help African farmers improve their livelihoods -- and positively impact society, the economy and the environment.

https://www.ted.com/talks/zac_goldsmith_how_to_boost_nature_based_solutions_to_climate_change

With the ongoing extinction of species, destruction of forests and melting of ice caps, one thing is clear: even with huge advances in technology, individuals alone can't restore the world's ecological systems. Lord Zac Goldsmith, the UK Minister for Pacific and the Environment, believes that while we each have a part in climate activism, governments can propel the movement even further using political will. By taking steps to preserve nature through policy, regulations and proper funding, Goldsmith shows how leaders can help reverse the dangerous cycles propelling climate change. "Nature can rebound incredibly quickly," he says. "It's up to us to make sure that happens."

The ocean is often thought of as a victim of climate change, in need of human protection. But ocean expert Susan Ruffo says that mindset needs to shift. From storing carbon to providing protection to coastal communities, Ruffo highlights the ocean's ready-made solutions to the climate crisis and asks: With more than eighty percent of the ocean still unexplored, what new solutions are waiting to be discovered?

https://www.ted.com/talks/alex_gendler_building_the_impossible_golden_gate_bridge

Stretching 227 meters tall, two towers were assembled to support California's Golden Gate Bridge. They were just one of the challenges facing engineers Charles Ellis and Joseph Strauss. Even before construction began, many thought the project impossible: the strait was home to powerful winds, constant fog, and earthquakes. So how was this iconic bridge created? Alex Gendler details the feat. [Directed by Anton Bogaty, narrated by Addison Anderson, music by Salil Bhayani, cAMP Studio].

https://www.ted.com/talks/richard_browning_how_do_jetpacks_work_and_why_don_t_we_all_have_them

In 1961, Yuri Gagarin piloted a spacecraft in humanity's first manned space flight. A week later, Bell Aerosystems debuted a gas-powered rocket pack that could fly 35 meters in 13 seconds. Unfortunately, engineers knew this short flight was all the rocket pack could muster. So why was a massive spacecraft easier to send flying than a single pilot? Richard Browning investigates. [Directed by Mitch Hearn and Lisa Vertudaches, narrated by Bethany Cutmore-Scott, music by Cem Misirlioglu].

https://www.ted.com/talks/daniel_h_pink_4_kinds_of_regret_and_what_they_teach_you_about_yourself

Regret is one of our most powerful emotions -- and also one of the most misunderstood. Over the past two years, author Daniel H. Pink has collected a trove of more than 16,000 regrets from people in 105 countries in an effort to better understand this mysterious emotion. He shares the key patterns that emerged (it all boils down to the same four core regrets, he says) and explains how to transform your own regrets in order to create the life you've always wanted to live.

https://www.ted.com/talks/yana_buhrer_tavanier_what_is_normal_and_what_is_different

The word "normal" is often used as a synonym for "typical," "expected," or even "correct." By that logic, most people should fit the description of normal. But time and time again, so-called normal descriptions of our bodies, minds, and perceptions have turned out to match almost no one. So what does normal actually mean— and should we be relying on it so much? Yana Buhrer Tavanier investigates. [Directed by Eoin Duffy, narrated by Pen-Pen Chen, music by Adam Alexander, Bamm Bamm Wolfgang].

https://www.ted.com/talks/sathya_raghu_mokkapati_the_greenhouse_in_a_box_empowering_farmers_in_india

For smallholder farmers in India, agriculture has long been an unreliable source of income -- crops that flourish one season can fail the next, thanks to heat, pests and disease. But climate risk is now making the profession nearly impossible. TED Fellow Sathya Raghu Mokkapati is determined to change that with "greenhouse-in-a-box": a small, low-cost, easy-to-build structure aimed at helping farmers weather sizzling summers, increase monthly revenues and grow more food with less water.

It's 1819. The US is preparing to make Missouri and Maine new states. One representative insists that slavery shouldn't be allowed in any new state. Another believes it should be a state's right to choose. A compromise is proposed: slavery will be allowed in Missouri and prohibited in Maine. Can you spot the problem with this compromise? Elizabeth Cox explores the middle ground fallacy. [Directed by TOGETHER, narrated by Jack Cutmore-Scott, music by Massassauga].

https://www.ted.com/talks/dan_jorgensen_how_wind_energy_could_power_earth_18_times_over

Over the last two decades, the wind power industry has grown at a dizzying pace. (Fun fact: a single rotation from one of the world's most powerful wind turbines can generate enough electricity to charge more than 1,400 cell phones.) Building off this exponential growth, Denmark's climate minister Dan Jørgensen lays out his plan to end the country's oil industry by 2050 and transition to a fossil-free future powered by wind energy.

If you're wondering why blackface -- mimicking people of African descent via stereotypes and makeup-darkened skin -- is a big deal, then perhaps a little history lesson can help demystify the outcry. Dwan Reece, curator at the National Museum of African American History and Culture, explains how this practice permeates the American psyche and culture (in theater, music, books and beyond) and why it's not simply harmless fun, but a legacy of oppression.

A self-declared "repair geek," Gay Gordon-Byrne is a driving force behind the right-to-repair movement, which aims to empower people to fix their stuff. She describes how the movement is gaining legislative momentum and breaks down how the global shift away from "throwaway society" can literally turn trash into treasure in a circular economy -- so we can all experience that "Yes! I fixed it!" feeling.

https://www.ted.com/talks/anna_malaika_tubbs_how_moms_shape_the_world

Mothers undeniably impact and shape history -- but their stories are often left out or misrepresented, says sociologist and author Anna Malaika Tubbs. This erasure limits policies to support mothers and their essential roles in society. Citing the remarkable lives of Alberta King, Louise Little and Berdis Baldwin (the mothers of Martin Luther King Jr., Malcolm X and James Baldwin, respectively), Tubbs emphasizes the need to shift the perspective on motherhood at a cultural level -- to better reflect the presence, power and influence of moms as our first leaders, caretakers and teachers. "Would the world be different today if we had been telling their stories all along?" she asks.

https://www.ted.com/talks/sophia_kianni_language_shouldn_t_be_a_barrier_to_climate_action

Most scientific literature is written only in English, creating an alarming knowledge gap for the 75 percent of the world who don't speak it. That's a big problem for climate change -- because it's hard to take action on something you don't understand.

https://www.ted.com/talks/emily_pilloton_lam_what_if_women_built_the_world_they_want_to_see

Only four percent of construction workers are female -- that's totally unacceptable, but it's also a huge opportunity both for women and for the trades, says youth educator and builder Emily Pilloton-Lam. She makes the case for putting power (and power tools) into the hands of young women and gender-expansive youth, dreaming of inclusive construction sites and daring to ask: What if women built the world they want to see? (Plus, Pilloton-Lam dazzles with a live demo of her own woodworking skills ... while giving the talk.)

Cronin investigates. [Directed by Josefina Preumayr, narrated by Addison Anderson, music by André Aires].

https://www.ted.com/talks/countdown_it_s_time_to_write_a_new_climate_story

Climate change is here, it's real, and it didn't happen overnight. Over the past 150 years, human activities like manufacturing, transportation, commercial agriculture and energy production have created a blanket of carbon pollution that's changed the Earth's ecosystems. But even though the climate crisis is deep-rooted and complex, we can't just give up. Transforming our world is urgent and necessary -- and we already have everything we need to protect the planet we call home. (Narrated by Don Cheadle)

https://www.ted.com/talks/gabrielle_walker_what_you_need_to_know_about_carbon_removal

What do woolly pigs have to do with climate change? They're part of a vital, ingenious and evolving strategy to take carbon out of the sky and store it safely -- in trees, soils, the ocean, buildings, rocks and deep underground. Every carbon removal approach takes some combination of natural resources, human ingenuity and technology, says climate thinker Gabrielle Walker. If we get the mix right, we can clean up the environmental mess we've made, reverse the processes behind climate change and give nature a chance to heal. "What goes up must now come down," she says.
